Convert Image to Circles/Dots

Question

Hi All, 
 We are currently investigating placing an image on an acoustic panel. We were intending to use 7 different hole diameters to create the pattern. 
 We have broken the image down to a simple grey tonal range and now would like to draw a grid and in each grid box analysis what colour is dominate then place a circle at the centre of the grid box. 
 Do you think this is something we can use GC for? 
 Thanks 
 Wayne

Hi Wayne, 
 Yes, there is an add-in that is built based on the sample project which is available for extending GenerativeComponents: https://communities.bentley.com/products/products_generativecomponents/w/generative_components_community_wiki/6148/image-uvsampler . 
 This will need to be built for specific versions of GenerativeComponents. I'll see whether I can update the C# project for CONNECT Edition and then make it available as an addition to that same Wiki post. 
 Regards, 
 Volker

Hi Volker, 
 Trying to load the dll and receive this error:

not a big concern, I followed your instructions and create a new DLL using visual studio and it all works perfectly. 
 thanks

Hi Wayne, 
 For a range of values "rv" from rv = 0.0 to rv = 1.0 you could use Round(rv * 11.99999 + 2.5, 0) to generate numbers from (inclusive) 3 to 14 with statistically even distribution. In the argument to Round, you would generate values from 2.5 to 14.49999, which would round to values from 3 to 14. 
 For a range of values "rv" from rv = 0.1 to rv = 1.0 you could use Round((rv - 0.1) * 16.1111 + 2.5, 0) to generate the same range of values in the argument to Round, which would yield values from 3 to 14, too. 
 The idea is that you scale the range you have so it fits in whichever gap you need it to fit. Usually, this is easiest with a "normalized" range from 0 to 1. For non-zero low values, you'd first scale the normalized range to the range you need and then offset by adding or subtracting the desired start value, respectively. Because Round() rounds up for values greater or equal to .5 and down for values less than .5 I suggest above to generate a range that in an even distribution would generate approximately the same amount of values rounding up and down to the lowest and highest desired numbers in the range, respectively. 
 HTH and best regards, 
 Volker
